(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 75'?) 2 Claims.

supporting a fastening element preparatory to and during hammering of the same; to provide an improved hammering device having a telescoping handle so as to permit the hammering of fastening elements at various elevations; to provide an improved hammering device having a pivoted hammer together with remote control means for causing striking movement of the hammer whereby fastening elements may be installed at elevated heights from the ground; and to provide improved elements and arrangements thereof in a hammering device of the character described and for the purposes set forth.

In accomplishing these and other objects of the present invention, I have provided improved details of structure, the preferred form of which is. illustrated in the accompanying drawing, wherein:

Fig. 1 is a side elevational view of the upper portion of a hammering device embodying the features of the present invention.

Fig. 2 is a side elevational view, taken at a right angle to Fig. 1.

Fig. 3 is a side elevational view of the lower portion of the device.

Referring more in detail to the drawing:

In Fig. 1, the numeral l designates a hammer ing device having an elongated telescoping handle Z'Which preferably consists of a pair of tubular members or sleeves 3 and t. The lower sleeve 3 is of greater diameter than the upper sleeve whereby the latter telescopes internally of the former. A thumb screw 5 is provided adjacent the upper end of the sleeve 3 for engaging and maintainin the sleeve 4 in adjusted positions relative to said sleeve 3 (Fig. 3).

A pair of parallel, flat bars or legs 6 are fastened to the upper or outer end of the sleeve 4 by spaced pairs of diametric bolts 1 and nuts 8 (Fig. 2). The upper portions of the legs 6 are offset laterally relative to the longitudinal axis of the bandle 2 by bending the inner portions of said legs rearwardly, or to the left, and their outer portions forwardly, or to the right (Fig. 1). In this manner, the outer and inner le portions are parallel to the longitudinal axis of the handle, with 2 said upper portions being disposed rearwardly or to the left of said handle axis, while the intermediate portions of said legs are inclined at an acute angle thereto.

The legs provide a fork or yoke 9 for pivotally supporting a hammer it which preferably includes a cylindrical handle or lever l l, of wood or other suitable material, and an enlarged, metallic head l2 mounted transversely upon one end of the lever. A transverse pivot pin or bolt 53 ex tends through the intermediate inclined portion of the yoke 9 and the lever ll is provided with a suitable opening It, as shown in dotted lines in Fig. 2, intermediate its ends for receiving the pin' so as to rotatably support said lever between the yoke legs. It is preferable that the opening [4 be formed adjacent the end of the lever opposite the head 52, whereby the weight of said head causes pivoting of said lever in a clockwise direction (Fig. 1). Suitable spacers l5 are confined upon the bolt it between the lever and the yoke, while said bolt is fastened in position by a suitable nut l 6.

For pivoting or swinging the hammer ID, a flexible line or rope I! is fastened by a screw eye IE to the end of the lever opposite the head and passes over a sheave l9 which is rotatably supported between the inner portions of the yoke legs by a bolt 20, spacers 2| and a nut 22 (Figs. 1 and 2). Suitable eyes 7.3 are carried by the sleeves 3 and 4 for receiving the rope I! and directing the same longitudinally of the handle. An annular weight member or ring 24 is slidably mounted on the sleeve 3 and is fastened to the lower or free end of the rope, whereby reciprocation of the weight relative to said sleeve causes swinging or striking movement of the hammer.

If desired, the outer or upper extremities of the yoke legs may be slotted transversely as shown by the numeral 25 for supporting a fastening element 2% in position for hammering (Fig. 1). A transverse plate 21 is disposed beneath or in wardly of the slots 25 for connecting the leg extremities (Fig. 2). The fastening element 26 is of the staple type and preferably carries a body 28, of suitable insulating material, having a wire conductor 29 extending therethrough. As illustrated in Fig. l, the wire conductor 29 engages within the slots 25 with the insulating body 28 resting upon the plate 21 so as to support the fastening element in position for striking by the hammer; however, the insulatin body could be eliminated with the element being supported by resting upon the plate.

Operation The operation of a hammering device constructed as decribed herein is as follows:

A fastening element 26, with a wire conductor 29 extending through its. insulating body. 28, is supported at the upper extremity of theyoke legs 5 by engaging the conductor in the slots 25 whereby the body rests upon the plate 21. The hammering device I is then elevated so as to raise the fastening element and conductor to the.- desired height and such height is controlled bythe ad.- justment of the inner sleeve 4 relative to the outer sleeve 3 of the handle 2.

Due to the pivotal mounting oi the lever" the hammer NJ, the weight of its head 12. maintains said lever in its retracted or clockwise position. Since the rope i1 connects the weight.- member 24 to one end of the lever, reciprocation of said weight member downwardly 0r outwardly oil the outer sleeve 3: swings the hammerv Win a counter-clockwise direction. so: as: to cause its. head to strike the fasteningelement. Release or inward reciprocation of the weigh-t member. results in. reverse; or clockwise pivoting of the: hammer to again permit striking, movement. oi. said hammer. Upon installation of the-fasteningelement,. the hammering device may be. readily disengaged therefrom and lowered. for. the installa.- tion of additional tastening. elements.

While I have. shown but one embodiment of myinvention,, it; is susceptible to modificationwithout. departing from. the spirit. of the. inventions I do not wish, therefore, to be limited. by. the. disclosures set, forth, butv only by the scope. of the. appended claims.

The. invention described herein-may be manufactured and used by, or for. theGovernmentof. the United States of America forgovernmental purposes without the payment of any. royalties. thereon or therefor.

I claim:

I. A hammering device includingan elongated handle, the handle comprising a pair of telescoping members, means. for fastening the members in adjusted tel'escoped relations. a pair of parallel legs secured to one end of said handle andhaving their outer ends offset relative to the handle, the outer ends of the legs having means for supporting a fastening element, a lever pivotally supported between the intermediate portions of said legs, an enlarged head mounted on the outer end of the lever.- and. adapted to strike; the fastening element upon swinging of said lever relative to the legs, a rope secured to the inner end of the lever and extending to the far end portion of said handle, a ring slidably mounted on the handle and having connection with the rope for swinging said lever, and a. sheave rotatably supported between. the inner portions of said legs for receiving said rope.

21 A hammering device including, an elongated telescoping handle, a pair of parallel legs secured to one end of the handle and bent upon themselves so'as to provide offset outer end portions, the latter having means for supporting a fastening element, a lever pivotally supported between the intermediate. portions: of the legs, an; enlarged head-a mounted: onthe: outer end. of the lever for striking the fastening element upon swingi-ngs'disaid. lever relative to. saidlegs, a. weight member slid-ably mounted upon said. handle; andflexihle' means; fastened: to-- anct extending fromv theinner' end of the lever to the Weight memberfor swing ing said lever: upon. sliding; movement: of: said weight; member.
